I suspect that colonizing Mars (or wherever else) will turn out to be much more than just an engineering problem. If we get things like food, water, atmosphere, and even gravity right, I think we’ll still find an endless list of requirements that we didn’t know were requirements… and some mystery problems that don’t seem to have any cause at all. Those problems will be because of factors we never thought of, or don’t even know how to detect.
There could also be surpluses/deficiencies in our diet or environment that will take years (or perhaps generations) to show up. Again, that would be because of unanticipated, and maybe unsolvable, problems.
I remember sitting in on a briefing from the Biosphere folks when they reached out for collaborating institutions. One of the things that stuck with me was that they discovered that trees that were not subject to wind failed to develop a healthy trunk and tended to fall over and die. That’s not something that the researchers had even thought of.
I suspect that there’s going to be a lot of that.
Interesting! Plus, that’s exactly the sort of weird, unanticipated thing I’m talking about. How do you plan for everything? You can’t.
The first human colonists (who are just ordinary people) won’t be the rich. They’ll be desperate people who are sold a dream of the future and treated as human lab rats.
Can I ask what year that was? We've known that greenhoused cuttings need an oscillating fan in order be able to hold themselves upright once they start to gain height for the 30 years that I've been growing that way. It's like a little work out for them.
It would have been something like 2005 or so. It may have been a known fact at the time, but they mentioned specifically that they were caught by surprise by the phenomenon. I didn’t fault them for it - the whole project was kind of a mess. I’m a biologist and I wasn’t aware of that, so it wouldn’t have occurred to me, either.
That’s weird though. You’d think they would have had multiple botanists on the design team who could have pointed that out.
I'm sure it was just that no one realized it would scale to trees, since that hadn't been done before. As far as I know you don't have to do anything special in that regard with small seed-grown plants in a green house, only cuttings that root from stems, and so have weaker roots at first and stalks that were previously branches. I'm sorry I sounded critical, I was just curious.
Also there's that documentary where the group that organized it was kind of cult adjacent. They weren't scientists first. Still very interesting and impressive they did what they did.
I could still see people trying to make it work for generations for some reason, many early colonists in the West died before stable states could be founded.
We for sure will need to exercise, because low gravity turns our muscles into mush.
